The is a 16-bit, general purpose parallel I/O port expander for I2C bus applications. The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB). The MCP23017 can be configured to operate in 8-bit or 16-bit modes. Lets look at the pinout   The MCP23017 is a +5V device. So we connect VDD to the …

Arduino and MCP9808 digital temperature sensor example

30th November 2016,   has blogged 9  posts

The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature sensing applications. The registers allow user-selectable settings such as Shutdown or low-power modes and the specification of temperature Event and Critical output boundaries. When the …

Arduino DHT22 temperature sensor example

30th November 2016,   has blogged 9  posts

In this example we use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor. The DHT22 is better than the DHT11 because it has a wider range of measurement, 0 to 100% for humidity and -40°C to +125°C for temperature. Also it has a …
